Browsing is a valuable way to learn about birds, however it is a brute force approach and not designed for identification.
A more sophisticated approach to finding a bird with specific field marks is to use the Step by Step Search.
You can also try the Wizard to find a bird, which uses a question and answer approach, but again it does not give you the flexibility of the Step by Step Search.
